a of this invention will become Patented July 18, 1933 UNITED STATES AARON KLOTZHAN, OF BALTIMORE, MARYLAND, ASSIGNOR T0 CORPORATION, A CORPORATION-OF MARYLAND PATEN T OFFICE MAY OIL BURNER ATOMIZER Application filed J'anuary 28, 1932. Serial No. 588,461.

This invention relates to atomizers and has particular reference to nozzles employed in oil-burners for atomizing fuel oil and ejecting the same into a furnace or other combustion device.

Among the objects of this invention is the provision of an atomizer with a whirling chamber of substantially permanent dimen-' sions for promoting'stability in quantity and physical characteristics of the dispersed liquid issuing from the atomizer.

A more specific object of this invention is the provision in the distributor of an atomizer of a jewel at thedistributing end for making t is part of the device effectively resistant to corrosion and Wear by the oil.

Other, further and more specific objects readily apparent to persons skilled in the art from a consideration of the following description when taken in conjunction with'the accompanying drawing wherein;

Fig. 1 is an enlar ed elevation, partly in section, showing the body, head and distributor of an atomizer, a flat top jewel being set in the distributor pin and a jewel in the tip of the head.

Fig. 2 is an enlarged top plan view of the distributor pin, showing t e tangential ducts for the flow of the oil from the body of the atomizer to the whirling chamber.

Fig. 3 is an enlarged fragmental View, illustrating the use of a jewel with a top cavity in the distributor pm and a jewel in the tip of the head.

Fig. 4 is a view similar to Fig. 3 and illustrates the use of a jewel in the distributor pin, but no jewel in the tip of the head.

Fig. 5 is another enlarged fragmental view in section. illustrating the use of a flat top jewel in the distributor. and a jewel with a whirling chamber in the tip of the head and ducts formed by one of the jewels and slots in the adjacent portion of the other jewel for delivering oil into the whirling chamber.

Fig. 6 is a view similar to Fig. 5, but with the oil ducts entirely within the jewel setting in the tip of the head.

The apparatus comprises the body 1 of hollow cylindrical construction connected at be used. The ducts are one end 2, to an oil supply pipe (not shown) and at the other end 3 to the head 4.. This head has at its tip 5 a jewel 6 securely set therein. This jewel 6 is preferably a natural sapphire, but other jewels such as ruby, diamond, or corundum may be employed. Also, the corresponding artificial jewels ma be used, although as yet they have not been found as satisfactory as the natural ones.

The jewel 6 has extending therethrough the small perforation 7 and the larger opening 8 continuous with the perforation 7. I

The distributor pin 9 extends from the body 1 wherein it is preferably centered by a suitable disc 10 and is rovided at its distributing end with a jewel 1, preferably like jewel 6. The top of the jewel 11 is brought to the bottom of the opening 8 in the jewel 6. Oil passes through the body 1 from the oil supply, then around the space 12 between the head 4 and distributor pin 9 and then through the ducts 13 to the whirling chamber formed by I the top of the jewel 11 and the opening 8 in the jewel 6. In the drawing, four ducts are shown, but any other suitable number may tial and when oil under pressure issues through these ducts into the whirling chamber it will be given a Whirlingmovement and will pass out through the orifice 7 in the form 0 a spray. The disc 10 has perforations 10a to allow the oil to pass therethrough.

This form of atomizer possesses superior advantages over those heretofore employed. VVit-h the jewels 6 and 11 forming the whirling chamber, there is assurance that such chamber will be permanent in size a-nd shape and will be practically unaifected by the oil whirling therein. Also, by having the sprayejecting orifice 'i' in the jewel, the size of this orifice will be permanent. This assures a steady flow of atomized oil from the atomizer with practicallv uniform physical properties as long as oil of the same kind, viscosity and pressure is delivered through the ducts 13.

In the modification shown in Fig. 3, the jewel ll is formed at the top with a cavity 14, the wall of which is adjacent to and contin uous with that ol' the opening 8 in the jewel 6. Here also the whirling chamber is defined by preferably tangenthe jewels (i and 11 and consists of the opening 8 and cavity l-l. liy providing the cavit v l-t. thecapacity ot' the atomizer is increased due toincrcasc in size of the whirling chamber.

In the modification shown in Fig. l, the distributor pin 9 is provided with a jewel 11 like that in Fig. 3, but there is no jewel in the tip of the head 4, the orifice and upper part of the whirling chamber being formed directly in the tip. This modification is not as desirable as the others.

It will be seen by reference to Figs. 1, 3 and 4 that the distributor pin 9 is in the form of a rod and rests in the disc 10. When in operative position. the top of the distributor pin and the jewel 11 bear against the head, the ducts 13 extending from the interior space 12 of the body 1 through the jewel 11 to the whirling chamber.

In Figs. 5 and 6, the distributor is part of the top of the body 1 and in this top is set the jewel 11, which may have a flat top as shown in these views or a cavity to form part of the whirling chamber similar to Figs. 1, 3 and 4.

The top of the body 1 is also provided with passages 15 extending to an annular groove 16,. whereby communication is established with the ducts 13 which lead to the whirling chamber. These ducts 13 may be at the junction between the jewels 6 and 11 and in the form of a slot in one of the jewels with the other jewel serving as a wall for the duct, as shown in Fig. 5, where the slot is in the jewel 6. Also, the ducts 13 may be confined to one of the jewels, as shown in Fig. 6, where passages 17 of sutiicient extent are provided in jewel 6 adapted to register with the annular groove 16 so as to afford communication between the ducts-13 and the interior of the body 1 irrespective of any displacements occasioned in the attachment of the head 1 to the body 1.

In the construction shown in Figs. 1, 3, 5 and 6, the oil bot-h enters and leaves the whirling chamber through openings in ewels, thereby affording permanence in control of a kind very highly desired but not heretofore obtained in devices'tor atomization of liquids. i

The present invention is not limited to the specific details set forth in the foregoing examples which should be construed as illustrative and not by way of limitation, and in view of the numerous modifications which may be affected therein without departing from the spirit and scope of this invention, it is desired that only such limitations be imposed as are indicated in the appended claims.
